[Q/A] Related to AWS Global Infrastructure Region AZ
Q5. What is AWS infrastructure?
Ans. The AWS Global Cloud Infrastructure is the most secure, broad, and dependable cloud stage, offering more than 200 fully-featured services from data centers globally. With millions of active customers and tens of thousands of partners globally, AWS has the biggest and most powerful biological system.
Q6. What is the difference between the AWS Region and Availability Zone?
Ans. AWS Cloud computing resources are housed in highly available data center facilities. AWS Regions are huge and generally scattered into independent geographic areas. Availability Zones are distinct locations within an AWS Region that are designed to be isolated from failures in other Availability Zones.
Q7. What is the main difference between an availability zone and an edge location?
Ans. Availability zones are a bunch of data centers that host all your resources. Edge locations are the small data centers that host static & dynamic web content.
Q8. What is the use of edge computing?
Ans. Edge computing helps decentralize data processing and lower reliance on the cloud. Edge computing has several benefits, such as Increased data security and privacy. Better, more responsive, and more powerful application performance.
[Q/A] Related to AWS Services
Q9. What are AWS Services?
Ans. AWS Services are:
- Deployment & Management
- Application Services
- Foundation Services
Q10. What is an IAM role?
Ans. An IAM role is an IAM entity that defines a set of permissions for making AWS service requests. IAM roles are not related to a particular user or group. Also lacks traditional long-term credentials such as a password or access keys. Instead, when you adopt a role, you are given temporary security credentials for your role session.

Q11. What is the difference between roles and groups?
Ans. A group is a collection of users with a given set of permissions assigned to the group. A role is a collection of permissions, and a user effectively inherits those permissions when he acts under that role.
Q12. What is AWS MFA?
Ans. AWS multi-factor authentication (AWS MFA) provides an additional level of security that you can apply to your AWS environment. You can enable AWS MFA for your AWS account and for individual AWS IAM users you create under your account.

Q13. What is the purpose of AWS Glacier?
Ans. The Amazon S3 Glacier Instant Retrieval storage class enables you to archive older media assets while making it available in milliseconds when needed. S3 Glacier or S3 Glacier Deep Archive can help you save even more money on storage expenses for media archives that don’t require millisecond access.
Q14. What is AWS Lambda?
Ans. AWS Lambda is a serverless computing service that lets users run code without managing servers. User pays only for the computing time they consume – there is no charge when your code isn’t running. With Lambda, users can run code for virtually any type of application or backend service.
[Q/A] Related to Storage Services
Q15. How many types of storage are there in AWS?

[Q/A] Related to Network Service
Q18. What is Amazon Route 53?
Ans. AWS Route 53 is a scalable and highly available cloud-based domain name system (DNS) web service that provides reliable and cost-effective ways to route internet traffic to AWS resources. It is also used for health checking of resources. It provides developers with an efficient and reliable way to connect users to internet applications without any delay, it still has a delay in servers or applications, but users may not be aware of it. It effectively connects user requests to AWS such as Amazon EC2 instances, Elastic Load Balancing, or Amazon S3 buckets.

Q19. Why should I use Amazon VPC?
Ans. Amazon VPC enables users to build a virtual network in the AWS cloud without VPN, hardware, or physical data centers required. User can define their own network space, and control how their network and the Amazon EC2 resources inside their network are exposed to the Internet. Users can also leverage the enhanced security options in Amazon VPC to provide more granular access to and from the Amazon EC2 instances in your virtual network.

Q27. Who should use CloudTrail?
Ans. Customers who need to track changes to resources, answer simple questions about user activity, demonstrate compliance, troubleshoot, or perform security analysis should use CloudTrail.
Q28. How is CloudFormation different from AWS Elastic Beanstalk?
Ans. These services are designed to complement each other. AWS Elastic Beanstalk provides an environment where you can easily deploy and run applications in the cloud. It is integrated with developer tools and provides a one-stop experience for managing the application lifecycle. If your application workloads can be managed as Elastic Beanstalk workloads, you can enjoy a more turnkey experience in creating and updating applications.

If your application requirements dictate more custom control, the additional functionality of CloudFormation gives you more options to control your workloads.
AWS CloudFormation is a convenient provisioning mechanism for a broad range of AWS and third-party resources. It supports the infrastructure needs of many different types of applications such as existing enterprise applications, legacy applications, applications built using a variety of AWS resources, and container-based solutions.
